Dunstan, this should do what you're looking for, based on the example that
you provided. I didn't test this code, but it should be pretty close.
function checkbox_group($cbarr,$formitem,$formname) {
foreach($cbarr as $k => $v) {
$ret.= '<input type="checkbox" name="'.$formname.'" id="'.$k.
'" value="'.$v.'" '. (is_array($formitem) &&
in_array($v,$formitem)?"CHECKED ":""). '/>\n'; }
return $ret; }
$chkboxes = array(
"bandc_cat" => "Barrel and Container Pumps",
"lab_cat" => "Laboratory Pumps",
"sanit_cat" => "Sanitary Pumps" );
echo checkbox_group($chkboxes,$_POST['cat'],"cat[]");
Hope that helps...!
